Problems with light / IES light

Hey everyone,

I am beginner and I need your help for a problem.
I have a problem with the IES lights in Rhino / V-Ray 1.5. If I insert the IES light in my construction, the light will be renderte sometimes in V-ray but not everytime!
All the paths to the *.IES file are correct. I have no idea where the problem is?!?
If one light works, I copied and paste it in the same scene and after the rendering, the first one only was shown!
Can you help me, where is my error?!

Best regards,

Hello kethos73-

I believe that this issue has been reported and it is fixed. An updated version of V-Ray for Rhino (1.50.216) that is now posted on our website.

Best regards,
